混合泥质砂岩人造岩样的实验测量

Experimental measurement of synthetic core samples for laminated and dispersed shaly sands

为揭示混合泥质砂岩的导电规律,测量了不同矿化度和不同含油饱和度的岩样电导率.研究了饱和不同矿化度盐溶液的人造岩样电导率与溶液电导率之间的关系,以及不同含水饱和度的岩样电导率与含水饱和度之间的关系.实验结果表明,混合泥质砂岩导电可以看作是层状泥质和分散泥质砂岩并联导电的结果.

In order to reveal the conductance laws of laminated and dispersed shaly sands, conductivity of synthetic core samples with different salinities and different water saturations is measured. The relationship between conductivity of core samples saturated with different saline solutions and conductivity of solution and the relationship between conductivity of core samples with different water saturations are studied. The experiment results show that conductance of laminated and dispersed shaly sands may be treated as parallel conductance between laminated shale and dispersed shaly sands.
